We look at the division of 242245 by 90 
We're looking to find how many times 90 goes into 242245.

Advancing to step 1:
2 divided by 90 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 90

On to step 2:
24 divided by 90 is 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 90

Going ahead to step 3:
If we divide 242 by 90, we get 2 and a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 180 from 242 leaves us with 62.
Grab the next digit (2) from the dividend, add it to 62, then carry on: 622 / 90

Let's proceed to step 4:
90 can be fit into 622 6 times, resulting in a remainder of 82.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we take 540 away from 622, we end up with 82.
Fetch the next digit (4) from the dividend, attach it to 82 and continue: 824 / 90

Let's proceed to step 5:
If we divide 824 by 90, we get 9 and a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 269.0
Deduct 810 from 824 and we're left with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 90

On to step 6:
145 divided by 90 is 1 with a remainder of 55.
The next digit of our result is 1. 
Result so far: 2691.0
If we take 90 away from 145, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
550 divided by 90 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 2691.6
If we take 540 away from 550, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 2691.61
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
The number 90 fits into 100 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 2691.611
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 2691.611, with a leftover of 0.001.
